Splitting

audacious: Audio player that has a nice Left-Right cursor key playback to easily find the places in the stream recording that you want to split/cut. Mark the Start and End Time from the recording that you made.

mp3spl: Using the Start and End Times from above, use them to split the recording. Don’t bother with the mp3splt-gtk gui app::

$ mp3splt recording.mp3 65.36 124.33 -a -o finalRecording

65.36: The start time from the original recording that the split will start

124.33: The end time from the original recording that the split will end.

-a: This option will slightly adjust the start and end time to fall on a silent period.

-o finalRecording: The final splitted file.

Tagging

easyTag: Use it to put mp3 tags in the final recording. Actually, any tagger would do. This is a, well, easy one!
